To all wlw-m it' may concer/n:

Be it known that L HAROLD BRIX, a ycitizen of the United States, residing at Arlingtonv Heights,A in the county of GookandState of lllinois,.have inventeda new and `useful Improvement in Anastomosis Clarnps` kof which the following yis a specification. f'

I My invention relates' nmore particularly to anastoxnosis clernpsjfor use in connection with Opere-.tions on the intestines and the. Stomach and mcrefespecellytp vvthe 'type `Off clamp comprising a centrally-disposed bar member, e pair *Cibers 'located at `Oppeste sides of the Centrally-,disposedmember,and mea-ns ,Carried by the l-atterfcr engesngthe outer ends of the pairs of bars'iand releasably hold f them in adjusted position relative l to the central bar. -A method commonly practiced in connectionlwith instruments of this-,Character consistsinjthe making of en incision inthe stomachvor intestines adj-acent to the portion thereof fto'jloe opera-ted on,l

' the-use of devices .of this Oharactenit is highlyfdesirablethat they be s0, construct- I .edthat"they,Inal Aloequickly and accurately manipulated. 'j .1,irthermore, in the` application of the device to usezand its remo'va'llfrom the patientyit'is necessary that the tightening Imeans referred to and lcarried by the central rbar ,Inemherf-:he'so positioned that they avill not present obstruction toitheready ap licati'on and removalofthe device.

'3 and f1, the 'openings .in the? shrinks 14C-and thruehwhihthepin 12- eX.- tends beinssufcently large' topermit ,the y devices.` l-tofassume theanted imstorlL 6,5 in Asidelclevation :ofthe ,upper portion of, the

. bars 21 to line up with the'respective shanlrsv resented at 25 to conform generally to the vcurved portions 17.0f the nuts 16 thereby forming sockets vpreventing accidental `disengagement of the fastening devices 13 from the Anotched* portions 24 of the bars 21.

Referring particularly to Fig. 2, it will be noted that the devices 13 which extend in oppositedirections from the bar 7 are offset relative to each other, and as. the bars 21 are preferably located in the same plane as shown in Fig. l2, the `slots 24 are offset in the 14, in` order that 'the Shanks 14 will, when these securing ,devices are thrown over to securing position, readily enter the respective notches A24. l l Y i 1t is desirablethat means be provided for preventing the 'tightening idevices 13 from swinging outwardly beyond a position in which ythey aline'with the central bar 7, the means shown for this purpose comprising a projection 26 on eachiof the Shanks 14 which, when the tightening devices are swung 'to a position in alinement with the bar 7, engage the bottom'wall 27 of the recess 11 and thus form stop-means limiting the movement of these tightening devices. lt is thus impossible for either one of the tightening devices to swing to one side of the bar 7 opposite that at which the slot vwith which it cooperates, extends, with the manifest advantage.

, In the use of thedevice the operator, prior to introducing the bar Vportion 7 through an incision, would swing the tightening devices 13, to the position shown in Figs. 3 and 4 in which position the springs l2O are placed under tension and serve to hold the parts in the 'position shown permitting the bar por tion 7` to be inserted through the incision without danger ofthe tightening devices moving to a position in which they would obstruct the properV insertion of the device into the desired position'. ln this connec tion it may bestated that the openings'in the Shanks 14 through which the pin 12 extends, areof slightly greater diameter than the diameterof the pin whereby these slianlfs 'may, in the movement of the devices 13 to the alined position, vshown'in Figs. 3 and 4, niovein the plane of the pin or, in other words, assume the canted position shown in Fig. 4 against the tension of the 'springs'20 Following the introduction of the bar portion 7 through vthe incision as stated, the outside bars 21 are swung toward the middle bar 7 to clamp the tissues at the opposite sides of the incision, between the bar 7 and the bars 21, the devices 13 then being swung outwardly and downwardly to aY positionin which the shanks 14 enter the notches 24, whereupon the wing-nuts 16 are tightened against the bars 21, seating at their curved portions 17 in the socket portions 25ct these bars, thevoperator screwing up these nuts to cii'ectthe y desired tension on the tissues clamped by the device. ,It will be noted that either one of the bars 21 may be released independently of the other as conditions may render it desirable.

The springs 2O tend to center the devices 13 in the recess 11 and when these devices are swung downwardly and outwardly from the position shown in Figs.` 3 and '4, they will be caused to accurately aline`with the notches 24 with which they cooperate and thereby insure their entryinto the notches without requiring any centering by the operator.

While l havev Villustrated and described a particular construction embodying my invention, l do not wish-to be understood as intending tolimit it thereto,vr as the same may be variously modified and altered with out departing from the spirit of my 'invention. Y

What I claim asnew, and desire'to secureQ by Letters Patent, is:

In a device of the character set'forth, the combination of a middlefbaiga'pair of Ybars located Aat opposite sides of saidmiddle bar, said bars being relatively' movable vand said pairs of bars containing notches in theirV outer ends, tightening devicespivoted side by side on the outerend of said middle bar to swing upon said pivot and relatively movable on said pivot in the plane of thelatter and vadapted -to enter said notchesfand engage said pairs ofbars, and spring means resisting relative movementjof said devices in the plane of saidpivot.' j

3. In ai device ofthe character'set forth, the combinationof amiddle bar, a pairfof V,bars located atopposite sides of said middleV bar,.sai d bars vbeingv relatively movable, the

outer end of said middle bar containing a recess, a pm extending across said recess,

tightening devices for engaging said pairs of bars pivoted side by side on said pin to swing upon said pin, said lrecess being longer than the combined thickness of said devices and said devices being relatively movable on said pin inthe plane of the latter,` and spring means interposed between the endwalls of said recess and said tightening devices, for the purpose set forth.

4. In a device of the character set forth,

the combination of a middle bar7 a painof bars located at opposite sides of said middle f ban-said bars being relatively movable and said pairs of bars containing notches in their outer ends, tightening devices pivoted side;

bars located at'opposite sides of said middlev bar, said bars being relatively movable,and

tightening devices for engaging said pairs of bars pivoted side byside on the outer end of said middle bar to swing upon said pivot, and` stop means limiting said devices each to rotation on said pivot in 'one direction only i beyonda position in which they aline with said middle bar.

' -.6. In a device of the character set forth, the'combination ofa middle bar, a pair ofv bars located at opposite sides of said middle bar, said bars being relatively movable and said pairs of bars containing notches in their outer ends offset relativeto each other, the outer end'of said middle bar containing a recess, a pin extending across/said recess, tightening devices comprising threaded Shanks pivoted side by'side on said pinand nuts screwing on said shanks, the length of said recess being ygreater-than'the combined thickness of said Shanks-said devices 'being ment of Vsaid kpin'and said shanks beingv adapted to enter said notches and said nuts to engage said` pairs of bars, and springs flocated between the end-walls of said and said pairs' of bars.
